Tenthredinidae is the largest sawfly family. It has 6000 species worldwide, with  900 European species and some 400 that are found in the British Isles. In size they range from 2.5mm to 15mm in length, and are either black or brownish yellow in colour.

 

The larvae mostly feed openly on leaves, but some are leaf miners, stem borers, or gall makers. The larvae that feed openly look like small caterpillars.

 

Parthenogenesis is common in this family and the males of some species are unknown.
